UNITED STATES PATENT OFFICE.

CHARLES-STEWART SOHENCK, on NEW YORK, N. Y.

CONVEYER.

SPECIFICATION forming part Of Letters Patent N0. 524,842, dated August 21, 1894. Application filed April 11, 1893. Renewed June 27, I894. Serial No. ,89 0 1 06 1 art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The special object of the invention is to remedy a defect in the pushplates used in conveyers and elevators to push the coal, sand or other material before them in the channel through which it is to be carried. The defect referred to is their liability to bend and thus cause the chains to come together. Attention is i called to my United States Patent No.

430,238, granted to me on the 17thday of.

J une, 1890, wherein these push plates are shown upon a single chain, but I now use adouble chain or one on each side with a different coupling and pnshplate, the whole constituting in practice a very great improvement.

Figurel of the drawings is a plan view of a conveyor partly broken away; Fig. 2 a transverse vertical section thereof; Fig. 3 a vertical longitudinal section, showing thepushplates on the conveyer chain; Fig. 4 a detail view of the drop steel forging or enlarged link to which the pushplate is attached; Fig. 5 a detail View, of the pushplate, and Fig. 6 a cross-section thereof.

In the accompanying drawings A designates the conveyer casing or channel which is supplied with coal, sand, or other material through a hopper A arranged above it and a gate B closing the said hopper; this gate being opened by suitable mechanism for that purpose.

two parallel conveyer chains 0 travel longitudinally near the respective walls thereof. At intervals along their lengths, I attach to the said chains push plates D which extend across the said channel and push forward the by the resisting material.

In the said casing or channel A thematerial within the same as the said chains move.

Each push plate is straight from its top to a point below its center, and thence to the bottom edge is curved forward sufficiently to slide obliquely in under the said material and thus lift it and lessen its resistance. This forward bending of the lower part of the push plate also braces it against being bent back To stiffen the push-plate still more I fasten to its back a brace plate E which extends nearly from end to end of it as shown in Fig. 5, and is T- shaped in cross-section as shown in Fig. 6. This is riveted to the said push-plate at various points on lines both above and below.

the middle of the pushplate and the rib of the said brace plate.

At intervals corresponding to those between the push-plates I provide the chains 0 withenlarged diamond shaped links 0, the

short transverse axis of each of said links being occupied by a vertical bracing crossbar 0, which is extended at its ends above and below the body of the linkto form two lugs c which are perforated in the direction of motion of the chain, each perforation allowing the passage of a bolt. The push-plate is provided at each end with a pair of deep indentations or slots 01' which receive the upper and lower bars of the link 0; also with bolt holes corresponding to the holes in the said lugs. These slots allow the ends of the push-plate to extend quite to the side walls of the channel or casing A without at all disturbing the chains 0, and also allow the said bolt holes to register. 'When the bolts are put through them and made to fasten the ends of thepush-plates to the said links 0 the conveyer is complete.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A pair of conveyer chains provided at intervals with enlarged diamond shaped links having perforated lugs at top and bottom in combination with pusher plates one of which is arranged to be bolted to each pair of such links through such lugs substantially as set forth.

2. A pusher plate for conveyers having a which register with the boltholes-in the said [0 pair of slots extending inward from each end push-plate substantially as set forth.

and bolt holes arranged as described, in com- In testimony whereof I afifix my signature in bination with a pair of conveyer chains having presence of two witnesses. correspondingly arranged links each of which CHARLES STEWART H will fit into the said slots at one end of the said push plate allowing the latter vto reach Witnesses;
